SEAT-LOCK FOR WAGONS.

SPECIFICATION 'OIming part of Letters Patent No. 767,589, dated August 16, 1904.

Application led May 28, 1904. Serial No. 210,231. (No model.)

To all whom, it may concern:

Be it known thatI, LEON P. MOORE, a citizen of the United States, residing at Smithville, in the county of Bastrop and State of rIexas, have invented new and useful Improvements in Seat-Locks for Wagons, of which the following is a specification.

rIhis invention relates to detachably securing seats to the side-boards of ...the bodies of farm-wagons; and it involves the use of clamps carried bythe seat and provided with springiaws which are forced to grip the side-board by means of cams or eccentrics preferablyT slightly flattened on one side at suoli a point that when in engagement the flattened sides prevent accidental disengagement.

In the accompanying drawings, Figure l shows a seat supported upon a wagon-body, the view being toward the inner face of one of the side-boards. Fig. 2 is asection on the line 2 2, Fig. 1, looking toward the right.

In the figures, A represents one ofl the sideboards of a farm wagon; B, a seat resting upon springs which are supported by and fixed to horizontal bars D, to each of which, near its ends, are secured clamping-hangers E. Each hanger has a body portion F, with an upwardly-turned hook G at itsY lower end and a downwardly-turned hook H at its upper end. In the lower hook rests the springsupporting bar D, whichis preferably secured by a bolt I. rests upon the upper edge of the side-board, which is not thick enough to fill the hook. In the space left by the board is placed a spring-jaw J, fixed to the upper part of the hook and having at its free lower end short inwardly-projecting teeth which do not normally reach the side-board. In the hook branch, beside which the spring-jaw lies, is pivoted a cam or eccentric K, provided with a handle L, by which it may be rotated in a plane transverse to the plane of the spring.

Jaw.

The cam normally rests against the jaw without pressing it inward; but when the cam is properly rotated it forces the jaw toward the opposite side of the hook, compelling it to engage the side-board when the hook is placed over the latter. Preferably the cam The downwardly-turned hook is slightly'fiattened at such point that when in engagement this flat portion rests against the flat spring-jaw. It follows that the cam cannot rotate in such direction as to loosen the grip without having positive rotating force applied to such an extent as to still further iiex the spring-jaw and force it slightly farther into the sideboard. Obviously the clamp is not likely to work loose. When' the clamp is loosened by proper rotation of the cam, the spring-jaw follows the receding face of the cam and returns to normal position out of contactwith the side-hoard by its own elastic force.

It is to be understood that each end of the seat is 4supported in the same manner and that at least one hanger at each end of the seat is clamped whenever it is desired to make the seat secure against displacement when the wagon is moving.

As shown, the cam is mounted in the outer side of the hook; but that is not indispensable to proper working. It is also shown as mounted by dividing the hook and bending the parts about a pintle M, supporting the cam, which lies between the parts; but other constructions may be adopted.

What I claim is- 1. The combination with a rigid, seat-supporting hanger having a hook adapted to drop over the upper edge of the side-board of a wagon, of a spring-jaw secured to the inner side `ofone branch of the hook, and a cam revolubly mounted upon the hook and arranged to have its surface approach or recede from the side-board as the cam is rotated.

2. The combination with a seat-supporting hanger adapted to rest upon the upper edge of the side-board of a wagon and having rigid parts projecting downward upon the inner and outer faces of said side-board, of a springjaw normally lying on the inner face of one of said parts, and an eccentric or cam arranged to force said spring-jaw toward the opposite part.

3. The combination with a seat-supporting hanger having at its opposite ends oppositelyturned, rigidly-connected hooks, of a normally retracted spring-jaw mounted in one of the hooks, and ahand-operated device mount- Sol IO with a handle for its convenient rotation and adapted to force the spring-jaw toward the opposite side of the hook to clamp an inter- Vening side-board.

In testimony whereof I have signed my name to this specification in the presence of two sub- I5 serbing witnesses.
